Mortalities occur sooner or later in all livestock production. Becuae of the relative numbers involved, large scale operations will have more dead animals requiring disposal than smaller frms. Mortality tends to be greater among some types of livestock such as poultry than other types such as beef cattle. Mass mortality may occur in livestock confined in structures such as barns but less likely to occur among livestock on the range. The regulation requires that mortalities be stored in a secure manner. Mortalities must be stored in a frozen state or kept refridgerated if they cannot be disposed of within 48 hours of death. Many intensive livestock operations have a separate freezer or refridgerated storage for this purpose. Producers who are able to dispose of mortalities within 48 hours of death rely on specially designed, covered steel or heavy duty plastic bins for secure storage.
